Hi there,

While the full screen output over the decklink card is butter smooth I get wonky playback over the regular GPU on my GUI monitors. This is not cause by the GPU (its a GTX 1080). The GUIalso shows smooth 30p playback but there's a regular pattern of stuttering in the picture.

But not only in the pictures. The playhead moving and the Waveforms are also stuttering. This is only in the color tab. When I switch to the Editing Tab it's smooth.

Seems like a bug ion R15, didn't have that in R14

Cheers

If you output 4:4:4 to the Decklink the GUI will be slow if you are showing the scopes. Try turning off either 4:4:4 or the scopes and see if that helps.
